Created attachment 104441 [details] View of a thread with duplicated emails Some of the emails I receive are duplicated in Kmail. See screenshot attached for some example. Not all the emails received are duplicated; it happens frequently, but not always. I could not find any pattern for the duplicated emails; However, I am the impression that it is related with emails coming from mailing-lists. If I use the "Delete duplicated emails", one of the duplicated email is deleted. I am using Kmail 5.2.3 from debian testing. I retrieve my emails with pop3. Using Kmail's view source option, I compared the two copies of a duplicate email (using ediff in a text editor). They were completely identical . I also had a look in the folder containing the emails (maildir). "Greping" with a string that appears in a duplicate email, I had only one match. This would means that the email is not duplicated in the maildir folder, but only in Kmail's display (also in akonadi db?). I run a akonadictl fsck and restarted Kmail, but it did not change anything. Feel free to contact me for any additional information I could provide. Thank you. Best regards

Do you have any local filters? If yes, could you see if maybe disabling them temporarily prevents the duplicates from appearing?
I do have local filters because they are very useful and something i don't want to be without. i shall try with them disabled for a week and report back to this bug report.
I've just done a few hours of testing using no filters on incoming emails. (i uncheck the "Apply filter to incoming messages" on each filter.) i now just click on the inbox and click 'Folders/Apply all filters on Folder'. I has so far not produced a duplicate email so its looking like filters on incoming is the culprit. I'll keep testing and try and find a related bug report on filters to update. opensuse:tumbleweed:20170317 Qt: 5.7.1 KDE Frameworks: 5.31.0 KDE Plasma: 5.9.2 kwin 5.9.3 kmail2 5.4.3 akonadiserver 5.4.3 Kernel: 4.10.3-1-default Nouveau: 1.0.13_2.2
